🌊 As I wanted to explore how combining multiple data sources can improve marine detection, I built a simple toy model using hydrophone data and marked individual tracking methods to estimate cetacean densities. I simulate the movement of individuals with a simple Individual-Based Model (IBM), and for the density estimation, I’ve used Kernel Density Estimation (KDE), though other techniques like Kriging could also be applied.

You can explore the model through this Streamlit web app:

Using #hydrophones to eavesdrop on a #reef off the coast of #Goa, #India, researchers have helped advance a new low-cost way to monitor changes in the world's murky marine environments.

I’m a Postdoctoral Fellow (#NSF OPP) in the Marine Mammal Institute at Oregon State University.

I earned my PhD from Scripps Institution of Oceanography (#NancyFosterScholar) and MSc from Moss Landing Marine Laboratories.

I use #hydrophones and #tags to study #bowhead, #blue, #humpback, and #Bryde’s #whale #migration, #movement, #behavior, #ecology, #predator-prey relationships, and ship strike risk spanning the #Pacific Ocean to the #Arctic Ocean.
